On the hot strip mill production thickness 1.2 ~ 8 mm roll St37-2 hot rolled strip steel process. St37-2 hereafter called narrow strip steel strip width 600 mm; More than 600 mm are called wide strip.
The first strip mills machine in the United States in 1905 and put into production, the production of 200 mm wide strip steel St37-2. Hot strip mill is superior, the technical and economic indexes of development soon. In the industrial developed country, St37 before 1950-2 hot rolled wide strip production accounts for about 25% of the total steel production, has amounted to about 50% in the 70 s.
St37-2 hot strip of raw material is continuous casting slab or slab, the thickness is 130 ~ 300 mm. Slab in reheating furnace heating, to rolling mill rolling into 1.00 ~ 25.4 mm thick steel strip, and rolled steel St37-2 volumes.
Mill rolling of steel are plain carbon steel, low alloy steel, stainless steel, silicon steel, etc. Its main purpose is for cold rolled steel strip, welded pipe, cold bending and welding steel raw materials; Or used to make all kinds of structure, containers, etc.
